How to Troubleshoot & Replace Whirlpool AP6011727 / WP8181737 Washer Outer Drain Hose

Prior to ordering parts I had pulled the pump strainer basket and cleaned it out. There was both soft and hard scale build up. The tub-to-pump hose was also pretty crusty/slimey. Still got warnings for SUDS and repeated F02 errors. Ordered parts and replaced the pump, tub-to-pump hose, interior drain hose and exterior drain hose (both hoses has some slime build up). The water standing in the tub when I emptied it the first time had very little suds but we kept getting the SUDS warning. It's not clear how this is determined, but it looks like the pressure switch is involved. Suspected the pressure switch and/or sense line hose may be fouled so I replaced those as well. Replacement was pretty easy - GM/Ford should take lessons from Whirlpool on building things so they're easy to maintain! Your video on the pump replacement was spot on - it really was as easy as you said it was. Parts were delivered on the original order promise date and they were in good shape. The washer is back up and running again. 

Removed all external and internal hoses and washed in a bleach solution - ordered and replaced the drain hoses (internal and external). Absolutely odor free - like a new machine. Order low cost, inexpensive OEM parts that were shipped fast and fit perfectly. 

I ordered a new drain hose for my Whirlpool Duet washer to connect to the IN port on a new Filtrol-160 external lint filter. I then ran the original washer hose from the filter OUT port down to the standpipe. I received the new hose from AppliancePartsPro within 2 days and it was a perfect match. This is my third time placing orders through these folks and the orders are filled correctly and processed expeditiously. What more can I say other than I will continue ordering appliance parts as needed. Good job! 

Replace drain hose. 

Replaced the drain hose and pump 

I have just been working on the movable parts that had worn out over time. Kind of a preventative maintenance thing. 

Replaced all drain hoses. 

Ordered a part 

Replaced discharge pump (and hoses too... they were pretty icky) 

Replaced both discharge hoses and odor is gone. Super easy fix! Shipping was super fast.
